This document provides a blue print and design plan for a Computer Science theory exam for Class XII. It outlines the following: 1) The content will be divided into 7 units covering topics like C++, OOP, data structures, databases, Boolean algebra and networking. Weightage of marks is allocated to each topic. 2) Questions will include very short answer, short answer type I and II, and long answer. Weightage of marks is allocated to each question type. 3) There will be no overall choice - all questions are compulsory. 4) Questions will be designed to target easy, average and difficult difficulty levels respectively. Two sample papers and marking schemes are also included

• Based on the above design, two sets of sample papers along with their blue prints and Mark-
ing schemes have been included in this document.
• About 20% weightage has been assigned to questions testing higher order thinking (HOT)
skills of learners.
